POWER-TRANSMITTING SYSTEM.

SPECIFICATION forming part of Letters Patent No. 790,801, dated May 23, 1905.

Application filed February 29, 1904. Serial No- 195,798.

To a, whom it may concern:

Be it known that I. ALBERT N. OLSON, acitizen of the United States, and a resident of Cambridge, in the county of Isanti and State of Minnesota, have invented a new and Improved Power-Transmitting System, of which the followingis a full, clear, and exact description.

My invention relates to a system of transmitting power.

The objects of my invention are to provide a system of the character mentioned to take the place of spur and bevel gears in automobiles and all kinds of machinery.

Further objects of my invention are to provide means for reversing and changing speed,

to do away with a large amount of friction on the journals, and to provide for the easy and efficient operation of devices of this character. Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view illustrating the principle of my invention and one manner in which I have contemplated applying it. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4 shows another way of applying my invention, in plan, with parts in section; and Fig. 5 is a fragmentary view showing another modification.

In the drawings, a represents a framework of any desired kind. 1 is a driving-shaft, 2 a sprocket-chain, and 3 a sprocket-wheel for reversing the fram e 4. The manner of driving the shaft is not part of my invention and any construction may be employed. Upon the framework (4 is placed a second frame, consisting of the parts 4, 5, and 6, carrying the shaft 1, and also a second shaft 7 parallel thereto. These shafts carry, respectively, the friction-wheels 8 and 9, which may be of any desired construction, and the two shafts are placed such a distance apart as to cause the two wheels to be in contact at their peripheries. The frame 4 5 6 is journaled at the points 10 and 11, so.that it may be inverted,

and the shaft 7 is preferably journaled in an adjustable block 12 in the frame 5, as shown in Fig. 2.

Upon one side of the wheels 8 9 are placed projections having grooves 13 extending around them, and in which operate pins upon the arms 14, which are operated by means of 4 a shaft 15 and lever 16. The shaft 15 passes through the center of the bearing 10, as shown. 17 is another part of the framework adapted to support another shaft 18 in a bearing 19 in such a manner that this shaft is at right angles to the shafts 1 and 7. Upon this shaft 18 are secured a pair of disks or wheels 20 21, It will be obvious that upon rotation of the shaft 1 the power will be transmitted directly from the wheel 8 to the wheel 9 and the disks or wheels 20. The wheels 8 and 9 will rotate in opposite directions, and the wheel 9 will transmit motion to the disks or wheels 2021. The two disks 20 and 21 will be caused to rotate in the same direction, and therefore the shaft 18, which is designed to transmit the power from the device, will be caused to rotate by both of these disks. The wheels 8 and 9 are preferably so arranged as to extend between the disks 2() and 21 at aslight angle, as shown in Fig. 2, so that by changing the angle of the frame 4 5 6 constant pressure can be kept on these two wheels and on the disks 20 and 21.

It will be obvious that upon manipulation of the lever 16 to force the disks 8 and 9 inward toward the center of the disks 20 and 21 the speed of the shaft 18 will be increased and that the speed of this shaft can be easily and readily controlled by this means. It will also be seen that upon the rotation of the whole framework 4 5 6, carrying the wheels 8 and 9 upon its axes 10 and 11, the position of the wheels 8 and 9 will be reversed and the rotation of the disks 20 and 21 will be reversed accordingly. A flexible means of transmitting power to the shaft 1 has to be used when this construction is employed in order to permit the shaft 1 to be rotated through the arc necessary.

In Fig. 4 I have shown another construction in which the main shaft 22 is not movable except upon its own axis. This shaft carries pivoted to it a framework composed of parts 23 24 and carrying a shaft 25 parallel to the shaft 22. Two friction-wheels 26 and 27 are carried by these shafts and are provided with grooves 28 and 29 in the same manner as the wheels 8 and 9 shown in the other figures. The framework to has a brace 30, provided with a bearing 31 for a hollow shaft 32, in which is keyed a transmissionshaft 33. The shaft 32 carries disks 34 and 35. The shaft 33 is considerably longer than the shaft 32, and the latter is capable of sliding upon it lengthwise, but not of turning with respect to it, on account of the long keyway provided. In this construction the frame 23 24 may be rotated about the shaft 22, and the shaft 32 with the disks 34 and 35 will then be caused to travel into the dotted positions shown in Fig. 4. It will be seen that this construction will permit the reversal of the shaft 33 without any movement of the shaft 22 except the rotation on its own axis. The change of speed will be accomplished in the same manner with this construction as in that shown in Figs. 1, 2, and 3. In the two forms shown the pressure on the disks 20 and 21 has been secured by placing the two wheels 8 and 9 or 26 and 27 at a slight angle to the shafts 18 and 33; but in Fig. 5 another method of accomplishing the same result is shown. Here the two friction wheels between the disks 2O 21 or 34 35 are placed with the line between their centers parallel to the shaft 18 or 33. One of the disks-say 21as shown in Fig. 5, is then provided with a spring 36 and collar 37 for the purpose of keeping this disk in close contact with the wheel 8 or 9. The disk to which this spring is applied would then have to be keyed to the shaft 18 or 32, as the case might be, in order that it might have a slight motion lengthwise of the shaft. Having thus described my inventi0n,I claim as new and desire to secure by Letters Patent- 1. In a power-transmission system, a pair of transmission members, means for rotating said members in opposite directions, a second pair of transmission members arranged to receive power from the first-mentioned pair of members;a shaft on which said second pair of members are secured and means for securing said second pairof members along said shaft.

9. In a gear mechanism, the combination with the main driving-wheel, of a supplemental wheel in engagement therewith, and lever mechanism for changing the position of the supplemental wheel from one side to the other of the main wheel, a shaft, a pair of disks splined thereto to drive the same, said disks being adapted to be moved longitudinally together upon the said shaft by the movement of the supplemental wheel, whereby the direction of rotation of the driven shaft may be reversed, substantially as described.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing Witnesses.
